Embossing in the form of grooves of mm was continuously performed by roll embossing. Thereafter, a separately prepared transfer paper (a 38 μm polyester film with a wood grain pattern printed by gravure printing using a PVC pattern ink) was continuously roll-transferred under the same conditions as in Example 1, and the polyester film of the transfer paper was was peeled off. Further, using a roll coater, a urethane paint containing 10% aluminum oxide powder was applied to a thickness of 50 μm. All of the above steps were performed inline. As a result of the above, a PVC tile with excellent surface abrasion resistance was obtained.
